Im running a 18 gallon rubermaid tub wiith 4 mature females under a 250 watt hps. Once done flowering the roots are huge and fill the contaner. Thats ariund 4 gallons per plant. I pulled roughly 24 grams a plant off my last harvest with 4 plants. When i grew soil, i used 1 gallon pots and pulled about 20 grams a plants dry. So i was thinking about making a 18 gallon ruermaid with 10 smaller plants except with dwc the roots will tangle easy.. So what if i trim the roots? not alot but keep them to about a gallon a piece?
